What does in the automotive industry GTI stand for?

A Grand Tourer Injection (from Italian Gran Turismo Iniezione) - abbreviated to GTI is a fuel-injection car model variant. Traditionally used for Grand Tourer cars, the term is now applied to various hot hatchbacks, even though they do not have the luxury traditionally associated with Grand Tourers. The 1961 Maserati 3500 GTI is the first car to use the GTI name that was later made famous in 1976 with the Volkswagen Golf GTI and also by the Peugeot 205 GTi launched in 1984.
